Source number estimation using eigenspace in direction of arrival (DOA) estimate

OCEANS 2009-EUROPE, 2009
A source number estimation using eigenspace is presented. It projects estimated covariance matrix of array signal into signal eigen subspace and noise eigen subspace respectively. Using the orthogonality between signal eigen subspace and noise eigen subspace, it is easy to differentiate the contribution of signal and noise by using the criterion value,

Comparison of conventional and subspace based algorithms to estimate Direction of Arrival (DOA)

2016 International Conference on Communication and Signal Processing (ICCSP), 2016
The Direction of Arrival (DOA) technology and researches are evolving areas in array signal processing. Biomedicine, sonar, radar, seismology, astronomy communication and earthquake widely use this estimation. We receive an incoming wave by sensing an array or a set of arrays, this sensed wave can be processed to derive many related estimation ...

Performance enhancement of aperture antennas used for estimation of Direction of Arrival (DOA)

2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014
In this paper, we propose a method based on signal processing techniques to improve the performance of aperture antennas, such as a parabolic reflector, used to estimate the Direction of Arrival (DOA) of a signal. Three signal processing algorithms are investigated, including the correlation method, which is used to make an initial estimate of the ...

Comparative Study of Wideband Subspace Direction of Arrival (DOA) estimation methods

The Journal of the Acoustical Society of America, 2008
Signal subspace Methods like ESPRIT, MUSIC and MATRIX PENCIL, provides high resolution Direction Of Arrival (DOA) estimation in comparison to traditional Delay and Sum and Capon methods, which are limited by sensor spacing. However underwater Acoustics signals are inherently wideband in nature and most of these Subspace methods works on narrowband ...
